next we divide

300÷428.660704987=0.69985421222

Answer 2

Answer:

$\frac{ 300}{ \sqrt{525} \times \sqrt{350} } = \frac{300}{ \sqrt{5 \times 5 \times 7 \times 3} \times \sqrt{5 \times 5 \times 7 \times 2} } \\ = \frac{300}{5 \sqrt{7 \times 3} \times 5 \sqrt{7 \times 2} } = \frac{12}{7 \sqrt{6} } \\ \frac{12}{7 \sqrt{6} } \times \frac{7 \sqrt{6} }{7 \sqrt{6} } = \frac{84 \sqrt{7} }{294} = \frac{42 \sqrt{7} }{147}$
